What does the term FC (First Crack) indicate in coffee roasting?

• A. Start of the roasting process
• B. Transition to light roast
• C. End of the roasting process
• D. Start of flavor deterioration

Answer: (B)

The term FC, or First Crack, in coffee roasting indicates a significant milestone in the roasting process, marking the transition to a light roast. This event occurs when the internal temperature of the coffee beans rises to a point where moisture inside the beans creates sufficient pressure, resulting in the release of steam and gases. This release causes the beans to crack audibly, which is a clear sign that they are reaching a specific stage in their development.

Understanding First Crack is crucial for roasters as it often defines the flavor profile and aroma characteristics associated with lighter roasts. It is at this point that the beans begin to develop complex flavors, and many roasters will make decisions about when to stop the roast based on the sound of the crack and the desired roast level. Therefore, recognizing First Crack helps in achieving the desired flavor attributes in the final coffee product.

In contrast, the start of the roasting process occurs before First Crack, while the end of the roasting process happens well after this point. Additionally, First Crack does not correlate with flavor deterioration; rather, it is the onset of favorable flavor development.
